APPARATUS FOR TREATING I-IANKS Application fiIed July 10, 1918.

To all whom it may concern:

Be it known that 1, Dr. YVILHELM Dijns'rELnn, a citizen of the Swiss Republic, and resident of Thalwil, Canton of Zurich, Switzerland, have invented a new and useful Apparatus for Treating Hanks of Textile-Fabrics with Liquids for the Purpose of Dyeing, Bleaching, ashing, lVeighting, etc., of which the following is a full, clear, and exact specification.

This invention relates to an apparatus for treating hanks of textile fabrics with liquids for the purpose of dyeing, bleaching,washing, weighting, etc.

Arrangement are known for the treatment of textile fabrics in hanks with liquids for the purpose of dyeing, bleaching, washing, weighting or otherwise treating the hanks, the hanks being stretched or distended in series between two rows of carriers, a stationary bath carriers being continuously rotated through the said bath about an axis parallel to the hank carriers, with or without another simultaneous displacement of these latter.

Furthermore arrangements are known for the treatment of textile fabrics in hanks, in which the hanks are carried vertically by means of two rows of carriers arranged parallel to each other in an upper and lower supporting structure in a stationary frame.

The subject matter of the present invention is an apparatus for the treatment of textile fabrics in hanks with circulating liquids for the purpose of dyeing, bleaching, washing, weighting or otherwise treating the hanks, in which a frame is employed comprising at least one series of parallel hanks on two rows of carriers, located in an upper and lower supporting structure, and is characterized by the fact that the frame is rotated periodically about an axis parallel to the hank carriers through an angle of 180, in order to effect a change in the positioning of the hanks, which are not stretched upon the carriers, in such a manner that the parts of the hanks, which are in contact with one of the hank carriers, are changed. By this means it is possible, by periodical rotation of the frame, to obtain a uniform action of the circulating liquid on the textile fabric.

structional forms of the invention are illustrated.

Figures 1 and 2 illustrate-a longitudinal sectional view and a sectional end View respectively of one constructional form of the invention, the rotatable frame of which is intended to accommodate a single series of parallel hanks.

Fig. 8 is a longitudinal sectional View of another constructional form of the invention, the rotatable frame of which is arranged to accommodate three series of parallel hanks arranged side by side.

Fig. 4 is a longitudinal sectional view of a rotatable frame arranged to accommodate two series of parallel hanks located one above the other.

Referring more particularly to Figs. 1 and 2, the frame A which is rotatably pivoted at a comprises an upper and lower supporting structure Z) in which the carriers a carrying the hanks e are inserted. These carriers consist of rods 0 having enlarged end portions (Z which upon being inserted in the grooves in the supporting structure I), maintain the desired uniform distance between the rows of hanks. In this manner it is possible to arrange a considerable number of pairs of carriers accommodating hanks e in a very small space, the hanks c in the position shown being dependent from the upper carriers a, hanging freely, and extending beyond the corresponding lower carriers. The carriers 0, and the hanks thereon having been inserted in the frame A, these carriers are held innnovably in the grooves b by some form of locking device which can be secured to the ends of the guide grooves h, so that upon rotation of the frame, the pairs of carriers carrying the hanks e are prevented from any displacement each to the other. The frame A completely charged with hanks is inserted in the casing B, its pivots a bein supported in a U-shaped bearing 7'. The outer end of one of these pivots is connected to a shaft 9 which passes through a stuffing box h in the wall of the casing B and is provided with a hand wheel 1' by means of which the frame A can be rotated in the casing 13.

A pump P cooperating with a distributing or spraying device C causes the treating liouid to be distributed over the textile fabric.

angle of 180 a further changein the position of the hanks is effected. If a periodical rotation of the frame takes place in this.

manner, a corresponding displacement of.

the hanks around the pairs of carriers oc curs, permitting the liquid to act on the textile fabric in an eflicient and uniform manner.

Instead of employing the hand wheel 2' the shaft 9 may be provided with a mechanical driving device.

The arrangement can also be employed with corresponding results if, instead of efi'ecting the circulation of the liquid by means of a pump, the circulating of the liquid is produced by transforming itinto foam or lather by means ofsteam or of air.

In the constructional form shown in Fig. 3, the frame A is so arranged that it accommodates three series of pairs of carriers 0 located side by side, all three series of pairs of carriers being rotated about a single pair of pivots a.

In the rotary frame A of Fig. at, two

series of pairs of carriers 0 are arranged one above the other, and both series of pairs of carriers are also rotated about a single pair of pivots a.

In addition to the above mentioned uni- 4 formity of action of the liquid on the textile fabric, the improved arrangement also possesses the following advantages:

1. All yarns, ribbons and tissues which are wound in hanks can be treated thereby.

2. By arranging the hanks side by side a relatively small space is occupied by the material to be treated and therefore a small quantity of liquid is necessary forthe treatment.

3. a The possibility of completely inclosing the device, if desired, with consequently less loss of heat.

at. The material can be carefully treated and disarrangement and tangling of the hanks is prevented.

W hat I claim is:

An apparatus for treating hanks of textile fabrics with liquids for the purpose of dyeing, bleaching, washing, weighting or the like, comprising a frame with two rows of horizontal carriers inserted in an upper and lower supporting structure on said frame and intended to receive at least one series of unstretched hanks, a casing in which the said frame is rotatably mounted about a horizontal axis, means for producing a circulation of the liquid in the said casing and means for rotating periodically the said frame about the said horizontal axis through an angle of 180 in order to effect a change of the hank parts in contact with the hank carriers and to render thus more uniform the action of the liquid on the textile fabrics.

In witness whereof I have hereunto signed my name this 16th day of June 1919, in the presence of two subscribing witnesses.

Correction in Letters Patent No. l,326,l66.

It is hereby certified that Letters Patent No. l,326,166, granted December 30, 1919, upon the application of Oscar E. Backus, of West Allis, Wisconsin, for an improvement in Hair-Cutting Machines, were erroneously issued to Ethel M. Bennett, as assignee, by mesne assignments, of the entire interest in said invention, whereas said Letters Patent should have been issued to the inventor, said Backus and Ethel M. Bennett, said Bennett being assignee of one-half interest only in said invention, as shown by the record of assignments in this ollice; and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the case in the Patent Oflice.

Signed and sealed this 10th day of February, A. D., 1920.
